What’s the value of “x”

X = 51

Step-by-step explanation:

A triangle = 180

3x-22 can be subtracted from 180, part of a supplementary angle pair

80 + x + (180-(3x-22)) = 180

80 + x + 180 - 3x +22

-2x + 282 = 180

-2x = -102

x = 51

plug back in to check

step-by-step explanation:

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
